Ringo Starr will feature on the upcoming reissue of the Who's rock opera Tommy.

The 1972 performance, featuring the 104-piece London Symphony Orchestra, sees the former Beatle in the role of Uncle Ernie adding vocals on "Tommy's Holiday Camp."

The rock opera's cast also features Pete Townshend as the narrator, Roger Daltrey as Tommy and John Entwistle as Cousin Kevin, along with, Rod Stewart as a local lad, and Steve Winwood as the father, among others.

"I always saw the Who's version of Tommy as more of a sketch and felt there was more that could be done with it.

The London Symphony project, I think, paved the way for more to come," Townshend says of the full orchestra version of the record.

Tommy, the remastered version, out of print since 1972, lands on CD, vinyl and digital download September 11.
